Glommer's map icon is pretty glitchy

Unlike Chester, the Glommer's Map Icon is acting weird on the map...

So you see that the icon is saved on map and when it come back to your screen it remake a new icon and it loop as long it reach your map range.

Even if yall know that no much players bring Glommer with them for travel, I use it cause of one mod I've made, so it's kinda annoying to see that there is 100 Glommer's Icons on my map.
